Hi, I m on lutera birth control . Last night I was extremtly sick & consistly throwing up, I took my birth control pill like always, but I believe I threw it up because I could not hold anything down. My husband and I are sexually active without any other protection. I just finished my period on 11th of this month, is there a chance I could get or be pregnant? And how soon can I find out? Should I keep taking my birth control?
